Rest assured that your clothing won't slow you down when you wear Castelli's Sanremo Speed Suit to your next triathlon. Castelli's Sanremo design minimizes drag by creating a virtually seamless junction between the slippery fabric of the top and bottom, while still retaining the comfort and flexibility of a full-length front zipper. Hydrophobic Instadry fabric is blindingly fast in the swim, and quickly sheds water. When it's time to ride and run, the light, breathable material dries quickly and helps you stay cool. The Sanremo also features their comfy KISS 3 Tri chamois and a spacious, aero rear pocket to carry your nutrition.
